to use a plunger to unclog a toilet
What did you eat last night? I had to trump the hump today when you were done.
To be interrupted in the moment of intercourse. This interruption ruins the moment. Similar to the cock block, but during sex.
Guy 1 - "Dude, not only did her friend unsuccessfully try to cock block me all night, when I finally put it in her I got a phone call from my mom."
Guy 2 - "Man, your mom hump trumped you!"
